COMBINATION FAUCET.

Application tiled December 20, 1922. Serial No. 608,044.

To all whom it may conce/rn.'

Be it known that JACOB T. JOHNSON, a citizen of United States, residingat Atlanta, in the Icounty of Fulton and State of Georgia, have inventedcertain new and useful Improvements in Combination Faucets, of which thefollowing is a specification, reference being had therein to thelaccompanying drawings.

The present invention relates generally to valves and faucets, moreparticularly combination hot and cold water faucets, such as are usedfor discharging hot or cold water or a mixture thereof for bath tubs,kitchen sinks, wash stands, barber shops, wall showers, and the like,and the invention forming the subject matter of the present applicationis an improvement in or another species in addition to the combinationfaucets disclosed in my Patent No. 1,336,236 granted April 6, 1920, andin my copending applications Serial Nos. 504,584 and 526,942 led Oct.1,1921, and January 4, 1922, respectively.

In addition to the general object in providing a practical and eflicientvalve or faucet of that kind requiring the operation of only a singleoperating handle or member, as in the patent and applications supra, itis the object of the invention to provide a novel and improved valvemember for controlling the flow of hot and cold water and the dischargethereof, and for the further purpose of directin the hot and cold waterto a mixing cham r in such a way that there is no liability for eitherstream of water being backed up, such as when one stream is delivered ata higher pressure to the faucet or valve than the other stream.

Another object is the provision of such a valve or faucet in which thetwo liquids do not comingle until they move in the same direction towardthe discharge outlet, to avoid back pressure on either stream of liquid,the two streams being prevented from having a headpn collision in thefaucet, to avoid jars and vibrations, as well as eliminating backpressure on either stream.

A further object is the provision in such a faucet or valve of novelmeans for breaking up or dividing the streams of liquid, so as to avoidthe whirling or agitated disin open position, portions being shown in'elevation.

Fig. 2 is a vertical section of the valve member taken on the line 2-2-of Fi 1, at right angles tothe line of view in rig. 1, the stem beingshown in elevation.

Figs. 3 and 4 are horizontal sections on the respective lines 3 3 and 44 of F 1.

Fig. 5 is a view somewhat similar toli 1, showing a modifiedconstruction, wit the valve member partly in elevation and partly insectim.

Figs. 6, 7 and 8 are elevations of valve members having 'different formsof ports therein.

Fig. 9 is a cross-'section on the line -9-9 of Fig. 8.

Fig. 10 is a crosssection of another modied form of valve member havingthe channels open at the peripheryU er opposite sides of the valvemember.

Fig. 11 is a cross section of another valve member showing a furthermodification.

Referring to Figs. 1, 2, 3 and 4, the body or casing 14 is of suitablemetal and has a vertical chamber 15 and hot and cold water inletpassages 1 6 and 17, respectively, leading to the opposite sides of asmooth cylindrical wall of the chamber 15, said Casin having suitablemeans for the connection o hot and cold water supply pipes. The lowerend of the casing terminates in a discharge nipple or nozzle 18, and thelower end of the chamber 15 is gradually reduced in diameter or tapered,as at 19, so that the wall of the chamber converges and merges into thenozzle or outlet portion 18 to provide a valve seat at the upper end ofsaid nozzle. The chamber 15 is internally screw-thread ed, as at Q0, ata point above the passages 16 and 17, and the upper end of the chamber15 is closed by a cap 21 threaded onto the upper end of the casing.

The valve member 2.2 is externally screwthreade-d as at 23;. near itsupper end to engage the screwthreads 20. for the longitudinal or axialmovement of the valve member within the chamber 15 when the valve memberis rotated, it being noted that the screwthreads between the valvemember and casing are located at that side of the passages 16 and 17opposite to the outlet ol' the casing. The valve member has a smooth cvlindrical surface fitting the smooth qvlindrieal vvall of the chamber15 below the screw threads. v

The valve stem or rod 24 extends longitudinally through the valve memberat the axis thereof, for turning the valve member, and the upperterminal of said. stem projects through the cap 21 and has a suitablehandle 25 for conveniently turning the valve member. A rubber or othersuitable gasket or packing Q6 is disposed around the stem 2l to bear andtit against the cap 21 on the interior thereof` so as to prevent leakageof the water past the cap. Said gasket or packingl is retained in placeby a metal disk or washer 27 seated on the upper end of the easing.although any necessary or suitable packing can be used.

In order to control the flow of hot and cold water, the valve member 22is provided at, opposite sides of its axis with the-longitudinalchannels or passages 2S and 39 extending to the lower end ot the valveniember, and the upper ends of said channels or passages open at theopposite sides o1' the valve member between the ends o l` the smoothcylindrical surface of said member. to provide the respective hot andcold water ports 30 and 31 to register with the hot and cold Waterpassages 1G and 17. The ports ll and 31 are so arranged that either otthem may fully register with the corresponding inlet passage, or the twoports may partially register with both inlet passages when a mixA tureof hot and cold water is wante'l. The contol of hot and cold water isobtained bv turning the valve member.

The discharge of water from the valve is prevented when the valve memberis screwed down, and,for this purpose` the lower end of the valve memberhas a depending linger or reduced portion 3Q. through which the valvestem or rod Qt extends. The linger or stud 32 is arranged rentrall)v ofthe valve member and easing. and the stem 2l has a collar or enlargementBil seating against or abutting the end of the linger 32. and said stemalso has a collar illV bearing against the upper end of the valvemember7 to secure the stem to said member, although other means ofattachment may be used, A Valve tip or washer 35 is secured to thecollar or terminal portion 33 of the stem 24, to be moved with the valvemember, and may be of rubber` fibre or other material to have acompression lit on the valve seat surrounding the outlet` so that whenthe valve member is screwed downwardly, the valve tip 35 will seat overthe discharge port or outlet with a compression lit to tightly closesaid outlet, thereby providing a compression valve structure." rl`hedischarge of any water from the easing is therefore shut olf when thevalve member is screwed down, and, furthermore, when the valve member isin this position, the ports il() and 31 are out of registration with thepassages 16 and 17, so that the valve member extends across and closesthe passages 1G and 17. while the Wall of the easing extends across andcloses` the ports 30 and 31. The inlet passages and outlet of the easingand passages of the valve member are therefore all closed when the valvemember is in closed position. to prevent leakage and to also relieve thepacking of pressure.

lVhen the valve member is screwed upwardly, the discharge port or outletis opened, and the ports 3() and 31 of the valve member can then bebrought into and out ot registration with the inlet passages for thedischarge of hot or cold water, or a desired mixture thereof when waterof an intermediate temperature is wanted. The pas sages or channels 2Rand-Q9 of the valve member will direct the hot and cold Water from theinlet passages longitudinall)Y in the valve member to discharge atopposite .sides of the finger 3Q into the mixing cham her between thedischarge end of the casing and lower end of the valve member. The, hotand cold water are therefore directed toward the outlet beforecomingling, and this eliminates the possibilit)1 of either stream beingbarked up or subject to back inessure. such as when one stream isdelivered to the valve at greater pressure than the other stream. Thevalve member also prevents the streams from mixing in the valve memberuntil they are discharged :from the valve member. The inflowing streamscannot. therefore, have a head-on collision in the valve.. such as wouldproduce a jarring or vibration of the plumbing, or'

the bark pressure on either stream.

Means is provided for reducing or eliminating the splashing or sprayingof the water in discharging' from the valve. Thus. the lower end of thevalve member is formed with an annular recess 2G surround ing the fingeror stud 3Q. and forming an annular shirt 37 at the end of the valvemember titting the wall of the casing and .spaced from the finger 32.with the passages or channels Q8 opening into thc recess 36 between saidskirt and finger. A fiat ring 38 is fitted between the edge portion ot'the skirt 37 and the finger 32, said ringv tit ting around the lingerwithin the recessed end of the valve member, and said ring,r has theannular series of apertures 89. so that the ring provides a strainer forthe discharge end of the valve member. Thus. the water flowing4 fromeither or both pas-- sages or channels of the valve meinber will passinto the recess 36, and the streams will be broken or divided up by theapertures IW. so that the Water will flow from the \alve member in jetsinto the mixingt eliamber. This will prevent the sudden rush ot' thewater into the mixing chamber. and the whirling motion of the water insaid elianr ber or through the outlet. and, as a result. the water has asmooth mixing action. t'oithe smooth discharge of the water from thevalve, without si'naving or splashingr objeetionably. As shown. the ringor strainer 38 a piece separate from the valve niember having a frictiontit with the sltirt Ib' and ngger in order that said rin;r eau beremoved for elearning or replacement.

Fig. 5 illustrates a moditieation. in that the screw threads of the.valve member 2;) are formed on a sleeve or collar 223 ieniov ablv fittedon the up )er end portion ot the valve member. and t'Ihat the serewthreads of the easing are formed in a bushingT "tl removablv fitted inthe upper end portion of the casinaT 14., whereb)Y said threadedportions of the valve member and easing can be replaced when worn out ordamaged. ln this construction. the valve stem "il" is also shown asbeiner integral with the upper enfl of the valve member.

Figs. G, 7 and 8 show the ports ti. Iii and 31C of the respeetive valvemember,`1 ot different shapes, each port havingl a large end for fullregistration with the worrespondiner inlet passage and a tail otlnarrower width for restrictingr the tlow as the larger or wider end ismoved awav from thtx inlet passage.

Fig. 9 shows the valve member 2;) with the opposite ports C and fill'otl the .shape shown in Fig, and the passages or ehair nels QS" and 29of the valve member are also of greater width than shown iu lfitr. il.said passages being: of widths equal to the lengths oithe ports. wherebyto prov ide t'ftr :i greater turniinr movement ot tite valvtl member ineontrollineY the tlow ot hot and wld water. which mav be espeeialljylesii able for showers.
